Suddennly, upon stopping after a short drive, my engine began to stutter and try to stall when put into ger to move either forward or backward. Has anyone have any thoughts about the problem is? Expert transmission shop hasn't been able to determine the cause.

 

Torque converter 'lock-up' fault/failure?
Should be some DTCs in the TCM?

 

My first thought was torque converter lock up. It's at a trans. repair shop now, waiting to see what the problem is.
